mearure bodies
(OP)
I want to measure the mass of an assembly, (analysis, measure bodies)i think the default will use steel as a reference material?
Can i window select and say, inherit from one particular component which has a material assigned to EG. aluminium, so that it tells me what the assembly would weigh if it were all in aluminium?

RE: mearure bodies
However you can do the following in the assembly file to perform this calculation:
1. Make the assembly file the work PRT
2. Promote all solid bodies into the assembly
3. Assign your material to the promoted solid bodies
4. Perform the mass calculation
5. Undo back to the step before the promotion in 2.
You can also use WAVE links in place of promotion. If you use WAVE links, then after step 2 you'd want to hide or suppress all components in the assembly.

It seems that the management of materials, requires to have the license.
But my solution is :
1° - Mass properties + Keep measure.
2° - Blank the "body mesurements" on part navigator.
3° - Create a tab on drafting
4° - Select tab.
4° - Right button on tab > Edit Using spreedsheet.
5° - Type : density + associative volume¹
6° - Enter formula for multiplication (density x associative volume).
7° - Enter formula for total weight.
8° - Exit spreedsheet.
See .prt on attachement (NX4).
¹ for associate volume use this formula : =exprval("p??")

"... the management of materials, requires to have the license."
And as for your proposed workflow, why invoke the spreadsheet? You can do all of that in the Expression system and save yourself a lot of wating around for Excel to launch and then to close after you're done. Now don't get me wrong, linking NX to a spreadsheet can bring some very powerful tools to bear on a problem, but for what you're suggesting, it's like killing flies with a sledge hammer.

To an Engineer, the glass is twice as big as it needs to be.
RE: mearure bodies
Not use the spreadsheet : do not allow to make the multiplication and addition formulas... if you have solution to make it without spreadsheet, i'm very interested, because as you say spreadsheet is heavy to used for this simple tasks...

Tools -> Materials Properties...
...and there was no additional license required other then Solid Modeling.
As for the Spreadsheet comment, the built-in Expression system is more than capable of creating any sort of formula which you would like with all of the standard mathematical operators as well as pre-defined math operators such as trig functions, as well as a large number of engineering functions, like motion and beam deflections, etc.
Anyway, for what it appears that you're attempting to do, the built-in function of NX should be more than adequate and you should need nothing more than the basic Solid Modeling module.

RE: mearure bodies
Thanks, i found the materials assigment...
But for spreadsheet, for me, it seems better and faster to use this way than the expressions....
